Sesame Street, a disappointment?

Nonetheless, and in spite of all its successes, I feel very strongly that Sesame Street has aimed too low, has misunderstood the problem it is trying to cure, and will be a disappointment in the long run. I also feel that it has misunderstood the nature and underestimated the opportunities of its chief subject, the three R’s, and its medium, television; and therefore, that even what it sets out to do in the short run it does not do nearly as well as it might.
